CT-6700 Digital Engine Tachometer

A digital engine tachometer to measure the revolution speed of petrol and diesel engines, motors on electric and hybrid vehicles, and other rotating bodies.

This compact tachometer supports 10 kinds of sensors with different uses including ignition pulse detection, gasoline and diesel engine rotation detection, and magneto-electric rotation detection. The rotation speed of an engine has now come to be able to be measured by an ECU crank signal, even when it is difficult to mount a detector on an actual vehicle.

Features

  • High response measurement- Analog output response; 1 cycle+8 μs or less of input signal –
  • Supports various sensors with different purposes
  • Automatic setting of trigger level with the Trigger Assist Function
  • Measurement by ECU crank signal of unequal interval pulses (option: CT-0672)
  • High speed digital data output by CAN* interface(option: CT-0671)
